Unit 4. Because and So: Giving Simple Reasons
Words from the text: because of, instead, available, dangerous, extra, volcano, airport, flight, ash, airspace, passenger, aircraft
A Because gives a reason. It joins two simple sentences into one. The reason comes right after because.
The airport closed because the ash was dangerous.
Airlines diverted their flights because Catania was not available.
Because вводит причину. После because всегда идёт целое предложение (подлежащее + сказуемое), а не просто слово.
B So gives a result. First we say the reason, then so, then the result.
The volcano was active, so the airport closed.
Catania was not available, so passengers needed extra transport.
So вводит следствие (результат). Схема простая: причина, so + результат. Перед so обычно ставится запятая.
C Because of also gives a reason, but after it we use a noun, not a sentence. Instead means 'in place of this' — it shows a different action.
Flights were canceled because of the volcano.
Planes could not land in Catania. They landed in Palermo instead.
Volcanic ash can damage aircraft engines, so pilots avoid it.
Because of + существительное (не предложение!). Instead значит «вместо этого» и показывает замену действия.
